Regularly rotation control with keys,Regularly Rotation control by keys

I have a question. There is a unit, the rotate character engine. I want to control this with keys, for example, when it is stationary, it returns when the key is pressed. GetKey commands don't work by the way

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class Rotate : MonoBehaviour {

 public float RotationSpeed = 1f;
  

 private void Start()
 {

 }
 void Update()
 {
     if (Input.GetKey(KeyCode.I))

         transform.Rotate(new Vector3(0f, 1f, 0f).normalized * RotationSpeed * Time.deltaTime);

     if (Input.GetKey(KeyCode.K))

         transform.Rotate(new Vector3(0f, 0f, 0f).normalized * RotationSpeed * Time.deltaTime);
     }

},
